| 摘 要： | 选用 6个具有特殊种皮颜色的花生种质材料搭配 1 0个杂交组合 ,测试了F1代 3个农艺性状、7个产量性状的杂种优势。结果表明 :特色花生杂交测试的农艺性状 ,主茎高表现杂种优势最强 ,产量性状 ,单株果重、单株仁重等综合性状杂种优势较强 ,各有 8个组合表现超亲优势 ,超亲优势率分别为 7 1 %～ 73 4%和 1 2 1 %～71 5% ;组合间杂种优势强度也有明显差异 ,总的看白皮花生母本效应较强 ,与红皮花生做母本比较 ,除饱果数平均杂种优势指数略低外 ,其余各性状均有较大幅度提高。

F_1 GENERATION HETEROSIS OF PEANUT VARIETIES WITH SPECIAL TESTA COLOR |
| |
| Abstract: | Six peanut varieties with special testa color were arranged in pairs of 10 cross combinations, and 3 agronomic characters and 7 yield characters were tested for their heterosis.The results showed that the main stem height had the most powerful heterosis among tested agronomic characters.Among yield characters,the syntheitc characters\_\_pod yield per plant and seed yield per plant had better heterosis,each has 8 combinations showed over\|parent heterosis with ranges of 7\^1%～73\^4% and 12\^1%～71\^5%,respectively.The heterosis among combinations also has significant difference.In all characters except the No.of filled pods per plant,the tested white variety has more powerful heterosis than red variety when they were used as female parent. |
